Brows the referees below to get to know the NBA’s referees—their tendencies, records, controversies, and backgrounds. We also offer a variety of Referee Intelligence Reports (RIR) that incorporate our unique crowdsourcing process to vector true officiating accuracy as well as other subjective elements (e.g., was the violation called by one or multiple refs? Was the call late? Is the call on a rookie, star, or veteran?). These hidden data points help us set our unique betting lines and help you win.
